I bough the Walden case for my iPad Air 2 and I love it! ( http://www.padandquill.com/cases-for-ipad/the-walden-collection-for-ipad-air-2.html ) I have a question for those who have used this case. I prefer to use the iPad case-less while I am at home; I like to use the case only when I travel (which I do a lot). Does the strength of the glue diminish with repeated un-casing? Pad & Quill's website (above) says- "Super-duper grip by Minnesota's 3M - clean release, washable-reusable"and I just want to check with other's experiences. Thanks!!
